Now Larry Rudolph, Spears' longtime manager, is telling the celebrity gossip outlet that, inferring from the information of her situation, the pop star should never perform again.

Rudolph told TMZ: "As the person who guides her career — based on the information I and all of the professionals who work with her are being told on a need-to-know basis — from what I have gathered it's clear to me she should not be going back to do this Vegas residency, not in the near future and possibly never again."

The superstar's manager touched on this being one of the contributing factors that led Spears to pull out of her residency. "It was the perfect storm," Rudolph told TMZ. "We had to pull her show because her meds stopped working and she was distraught over her dad's illness."

Additionally, Rudolph adds that Spears has always made the decisions of when and whether or not she wanted to continue working. However, if it was up to him, he wouldn't want her to work again until she's "physically, mentally and passionately" prepared — even if that time never comes.

"I have no desire or ability to make her work again. I am only here for her when she wants to work," Rudolph continued. "And, if she ever does want to work again, I'm here to tell her if it's a good idea or a bad idea."
